Definitions

  • the invention relates to a contactor, in particular a power or auxiliary contactor, with a contact system accommodated in a housing and with a magnet system actuating the contact system, the housing being closed off at the end remote from the fastening side by a cover, the contact system also having contact rails Has contact connection screws and fixed contact pieces as well as bridges with movable contact pieces which can be actuated jointly and act as openers and / or closers.
  • contactors of the aforementioned type are known in practice in numerous designs. In all of them there has been a major disadvantage, which can be seen in the fact that the connection wiring options are very cumbersome.
  • contactors are usually installed in rows close to each other in switch cabinets, with the mounting levels, usually with the interposition of U-shaped mounting rails, running vertically. In this case, the contactors are generally used close together in horizontal rows, so that the connecting lines run up and down and are brought together in channels between the rows of shooters.
  • connection screws are located one above the other for the wiring, ie in vertical planes to the mounting level of the control cabinet, if the contact connection screws are provided in two or more levels in the contactor, which run parallel to the mounting level .
  • the wiring is first carried out on the contact connection screws, which are located in a level closest to the mounting level. Only then can you do the wiring on the contact connection screws in the level or levels men who are at a greater distance from the mounting level of the control cabinet.
  • the present invention has for its object to provide a contactor in which there is a simple handling of the connection options of the wiring and in which the wiring to the top and to the choice lower contact terminal screws or vice versa can be made without increasing the width of the contactor specified in practice and limited depending on the number of poles.
  • the contact rails are arranged with their contact connecting screws offset in planes at different distances from the fastening end of the housing such that each contact connecting screw is freely accessible when the wiring is provided.
  • the invention is preferably used for power contactors up to 7.5 KW and for auxiliary contactors up to 20 A continuous current, optionally for four and eight contacts.
  • the contactor has a housing made of plastic, in which a contact system and a magnet system actuating the contact system are accommodated, the housing being closed off at the end remote from the fastening side 1 by a cover 2, the contact system comprising contact rails 3, 4 and 5 Contact terminal screws 6, 7 and 8 and with fixed contact pieces 9, 10 and 11.
  • the contact system includes movable contact pieces 12, 13, 14 and 15, which are each seated on only half of the bridges 16, 17, 18 and 19 shown in FIG.
  • these bridges in a manner known per se in a ge common bridge girders 20 are used, with the interposition of springs 21 in corresponding recesses.
  • the contact bridges can be used in such a way that they either act as NC or NO contacts.
  • the housing which encloses the previously explained contact system, is divided into planes running parallel to the housing mounting plane, namely ⁇ this housing consists of a lower housing part 22, a housing part 23 arranged above it and the cover 2 or, if a switching chamber base is interposed, a further housing part .24.
  • the contactor according to FIG. 1 can thus be converted from a four-pole contactor into an eight-pole or vice versa in a few simple steps.
  • the lower housing part 22 with the foot part 25 largely encloses the magnet system, specifically the core 26 with short-circuit rings 27 and coil 28 as well as the vertically movable armature 29, which, however, protrudes upwards in the lowest position after removal of the housing parts 23, 24, that it can be easily lifted off and the other parts of the magnet system can be removed from the housing.
  • the anchor 29 is in common with the bridge holder 20 in a suitable manner connected actuation of the contacts.
  • a rubber plate 30 is provided between the core 26 and a mounting plate 31.
  • a movable in the direction of the arrows shown slide 32 is provided, which engages in the right position with its nose 32a behind the edge of a U-shaped mounting rail 33 of the cabinet, while the opposite edge 33a U-shaped rail for insertion can be pushed behind a notched part 31a of the fastening rail 31.
  • a transverse strip-like projection 30a of the rubber plate 30 presses against the edge of the U-profile from above and prevents the contactor from moving laterally on the profile.
  • FIGS. 2 and 3 in particular illustrate in connection with the right part of FIG. 1, that the contact rails 4, 5 with their contact connection screws 7, 8 are arranged in planes at different distances from the fastening end of the housing 1 so that each contact connection screw 7, 8 is freely accessible when the wiring 34 is provided.
  • the contact rails are preferably arranged in two planes spaced apart from one another, the contact rails 5 of the cover-side plane being chosen to be shorter than the contact rails 4 of the other plane.
  • the contact rails 3 and 4 are shaped within their planes in such a way that the fixed contact pieces 9, 10 and 11 of the contact rails provided in the two planes each lie in pairs on perpendicular to the housing mounting plane 1.
  • the contact rails of at least one level, in the exemplary embodiment according to FIG. 2 the long contact rails 3, 4, are provided with an inclined part 3a or 4a.
  • the contactor is selected with eight poles. From Figures 2 and 3 one sees two further contact connection screws 35 and 36. These are the contact connection screws for the coil 28 of the magnet system, namely these contact connection screws are arranged in the area of the plane of the contact rails 3, 4 or their contact connection screws 6, 7.
  • spring contacts (not shown) are provided on the division plane 37 (FIG. 1) between the housing part 22 of the magnet system and the housing part 23 of the contact system two parts exist, one part. The underside of the housing part 23 and an anceren part on the top of the housing part 22.
  • guides 2a, 24a are provided in the switch chamber base 24 and in the cover 2, which run perpendicular to the housing mounting plane 1 and are assigned to the contact screw 6, 7, 8, for the use of a screwdriver shaft.
  • These guides are expediently designed as cylindrical holes, the diameter of the holes being selected to be smaller than the screw head 6a, 7a, 8a of the contact connection screws.
  • the contact connection screws 6, 7, 8 and 35, 36 each cooperate with clamps 44 (FIG. 7) that open after two opposite side surfaces 42, 43 of the switching chamber base 24, so that the connecting lines 34 can be inserted one or more times.
  • the terminals are expediently provided with self-opening clamping disks.
  • the clamp 44 has an essentially rectangular frame. When the ends of the connecting lines 34 are inserted into this open frame and the contact connecting screw 7 is actuated, the lower screw end presses on the fixed contact rail 45 corresponding to the contact rails 3, 4 and 5, so that the frame of the terminal 44 with the connecting lines so long is moved upwards until the connecting cables are tightened.
  • other screw connections with simple machine screws or solder connections or flat plug connections can also be provided for fastening the connecting lines.
  • this can be fiction switch according to contactor in a simple manner to other practical applications, by replacing the contact system with one or more switching chamber bases for another contact system, the contact systems optionally containing mechanical and / or electronic components.
